Improvement in breech-loading fire-arms



`M, RGBINSGN, OF

orrnn JAY, new Yorin.

Specification forming part of Letters Patent NG. g dated May 25, 1875;application filed April 17, 1875.r

To all ywhom it may concern:

Be it known that I, Gavin lil-Roninson,

or" Upper Jay, in the connty oi' Essex and State oi' New York, haveinvented certain new and nsefnl improvements in Brooch-Loading Fire-A1-nis 5 and l' do hereby declare the following to be a full, clear, andexact description of the and the nature or" niy invention consistsprincipally in an improved construction oi' extractor-bar adapted to beraised and lowered `so as to catch behind the riin of the cartridge.

Also,in the arrangementtherewith of a spring for throwing ont the cartidge5 and in the construction of the breech-l-loot` when conibined withthe guard-lever and extractor, as hereinafter more inlly set 'forth andelaii'ned.

IThe accompanying drawin i'nlly illustrates my invention, and in which Arepresents the frame, l the hammer, C the barrel, D the innord-lever.IL" the ieroendioularslidin breechbio-cir, G the horizontalsliding breech-block, l the extractor-bar, and J the slningforthrowing;` ont the old shell.

The gun operate-:l by the guard-lever. To open the breech this lever isthrown forward far as possible, the cartridge placed in the top oi theframe, and then the guard-lever closed baci: to its former position, andthe gun is ready to ire. After the gun is tired the guard is thrownforward again, and the old shell is thrown ont by the spring J, and thegun is half-cocked at the saule time.

The guard-lever l) is at its forward end piroted to a proie-ation, et,on the under side near the forward end of the horizontally s.id ing'breech-bloei; G, and a suitable distance in rear of sai? forward end itis formed with an arm or projection, which is pivoted in a deep grooveor slot in the perpendicnlarlysliding' breech-block E, thns beingdirectly attached to both crecen-blocks without any in terlnediate linksor connections, and operates extractor-bar botlrblocks simultaneously;or, in other words, one breech-block forms the ulcrurn While tho otheris being moved, and Vice versa, and both operated by the same lever.When'the breech is closed, the block E forms a perfect brace behind theblock G. i

The two breech-blocks E and Gare provided respectively with thefiring-pins. b and d, which are so arranged that the gun can not be reduntil the breech is perfectly closed, as only then the two tiring-pinsare in line with each other.

The extractor is a sliding bar, formed with a catch, e, to talreghold onthe flange. of the cartridge, said sliding` bar working through theira-ine A in a slot or groove under the barrel. The front end of theextractor-bar I is split and spread, forming a springq f, on that end,to hold the bar sufficiently rni at that end, so that the rear end oftheextractorbar can be raised to catch on the rim orlangc ol' the shell.The rear end ofthe extractor is raised andV lowered by means or anincline in the projection a or' the breech-block Gr, working,` through aslot in the rear end of the extractor-bar, so that both in opening andclosing the breech, said block` will nieve a short distance beforemoving the extractor-bar backward or forward, and during that firstInoveinent of the breech-block the extractor-bar is raised or lowered bysaid incline. It maires no ditl'erence whether the cartridge is pushedinto the barrel ahead 0r behind the extractor e, as the extractor isthrown down out of the way when the breech is closed, and thrown upwardinto position to catch the rim of the shell when the breech is opened.rihe shell is thrown ont by the spring J, which is attached either tothe frame or barrel, as deemed most convenient. When the guard is thrownforward the spring snaps up through aslot in the l, throwing the shellout,and the spring is so formed that as soon `vas the guard is startedback the spring is thrown down by the extracting-bar.

Having thus inlly described my invention, what claim as new, and desireto secure by Letters Patent, is-

-l. The extractor-bar I, connected and oombined with the breech-block byan inclined slot,

so that its Working end is raised up behind thel rim of the cartridge,substantially as specified. i l

2. In combination with the extractor-bar I, constructed and arranged tooperate by means of the inclined slot, as specified, the spring Jattached to the under side of the barrel, and

provided. with a projection upon its end adapted to enter a slot in thebar I for the purpose of throwing out the cartridge, substantially asspecied.

3. The sliding block.- G,. constructed with projections a a', wherebyconnection is made ORVIL M. ROBINSON.
